Abstract [en]

In modern society of industrialization, there are more and more trucks running on the roads transporting raw material or finished goods. With the rise of traffic accidents between cars and trucks, we need to put more attention to the tail of the truck. The authors design a device which can be fixed on the rear beams of the truck chassis. It’s called anti-collision equipment to avoid the cars crash into the truck tail. Although there are many available anti-collision solutions on trucks, studies show that there are still areas for improvement. The truck we choose to study is the heavy-duty truck of Jiefang J6M which is one of the mainstream models in China. The rear space of the truck is about 2400 mm (Width) × 2000 mm (Length) × 1050 mm (Height) and we design the device according to that size. Figure 1: Anti-collision Equipment Applied on Truck In other to achieve a better design, the authors study the literature and theses about energy absorption board, non-Newtonian fluid damper and thread shearing absorber. All of these three shock absorbers were combined together to make the design useful for different impact intensity. The height of the anti-collision is made adjustable for on-road and on-working site use. The authors design all the devices with Autodesk Inventor and validate material and dimensions by FEM Abaqus simulation. MATLAB simulation is used for calculating of fluid damper shock absorption. To make the best choice, the authors consider economic and reusability factors too.
